One of the primary objects oi thisinventionis to provide a small and compact dispensing-mechanism. whichis operatively associata'blewitha "conventional crown type cammea'nsbeing, therefore; especially provided for mountihg the dispensingmechanism in'thecan. r r 1 Another object of this invention isto-lprovide a pumping mechanism; operativelyi'disposed in I the can andto provide an operating means; disposed exteriorlyof and mounted on thecan',"the operatingineans being'reactive to' a slight manual pressureforeffecting a pumping stroke ofthe pumping mechanism, whereby a"predetermined amount of fluid is ejected. from the-can; g J Theseand'a'ncilla'ryobjects-and Structural featureseffmerit are attained 'bythis invention, as set forth in the followingjdescription and:illustratedin'the accompanyingidrawing, wherein'z'" 1 Figure 1 is 7 anenlarged side Y elevational view of the' di'spensing mechanism;illustrated in operative attachment to a conventionalcrown type can I .i.7 .r ii 5' Figure 2- isa -vertical sectional view of the can and Iillustrating --i-n section the pumping means and .cperatingm'eanstherefor; as well asflthe dis- Figure 3 is a transverse v sectionalview'taken canines-3 ofFigureZ.

Referring now mor'eparticularliy to the .accom- I panying drawing, thehand operated dispenser lfi includes a-dispensing mechanism 12, which isoperativelyassociated with a. container l4. The

container l-4 is a co'nventional. crown type can, formed with a mouthlG,having an outer jbead 18.

having an inner mouth 26 and a terminating flange 28.Circumferentiallyspaced vertical' slots 30 are formed in theskirt'permitting expansion of 'the fiange and skirt-overcthe beadLZG,upon inountin'g'the head 2ll'on the can. The :flange :28 "is adapted to'gripontothebead 26 in an even pressure contact therewith, the "mouth2616f the skir't encompassingthe "bead and zlocating; the head 20 in atransvers'eposition onathe-lmouth.

A; vertical vpassage 32 is formedin the headan'd aligned with'the-centerof the mouth ofctheican, the upperend of the passage being threaded fordof a. cap

. o ;2 claims; (Cl. 222-340) are carried by the tube and suspended orplug 34. A vertical bore 36 is formed in the 'pl'ugto accommodateanoperating rod 38, having an enlarged outer end :46; A manually actuableoperating means .42- is provided .and operatively connected to the rod38 for 'raisin'gthe rod inthe passage and bore 7 1 .A substantiallyelliptical shaped'handle 44 is provided and isformed with a lateralmounting flange 46 at one end, the mounting. flange being aflixecl toand projecting laterally from the top surface of thehead. The handle 44isspaced outwardly from and disposed at right angles to the head, inorder that the handle may be 10- cated-in-engage'ment of the side wallof the can and, in furtherance of this, a U-shaped resilient clip 48 iscarried by the handle, adjacent the opposing end thereof. The clip 48encompasses a portion of the side of the can below the mouth andas'sistsin the mountingofcthe head 20 on the m0uth.- v1.

' The lifting means 42 includes a mounting plate 50, which is affiiredto the flange 46 and is'fo'rmed with upstanding ears. A lifter 52 ispivotally supported by the plate 50, the lifter being attached to theplate by a link 54, one of the terminals of the link being pivoted tothe upstanding ears of the plate and the opposing terminal being pivotedto the'lifter 52, A contact end 56 of the lifter is offsettherefrom andis formed with an openin 58 for the reception of the rod 38, the contactend 56 being engageable with the underside of the enlarged or ball end40 of the rod for' efiecting, upon the applicatiorrof manual pressure tothe'outerend of anupward movement of the rod 38." a a a The lower' endof the passage 32 is threaded for the reception of the upper threadedend of a tubular conduit 60, the conduit depending there- ;from-into'thecontainer. A gasket 62 is circumposed n the upper end o" fthetubeand'held in a fixed position by a locking nut 64 engaged' on the upperthreaded terminal of the tube, the gasket being positionedin'the mouthof the container andconstituting'a closure, with the undersurface of thehead *resting on the outer edge of the mouth above the bead, as seen inFigure 2.

An outwardly projecting lateral shoulder 66"is formed on the lower endof the tube and a pair of telescopically arranged pumpin members -68 ina rested the lifter,

position on the shoulder 66 7 The pumping members 68 include a sleeve10,

'havinga lateral inwardly directed flange 12 formed on its upper end andengageable on the shoulder'GB, the flange" constituting a stop forlimiting the downward movement of the sleeve on the tube. A spring M isconcentrically coiled on the tube 60, the spring bearing at one endagainst the locking nut 84 and, at its opposing end on the flange 12. Acylinder 16 slidably encompasses the sleeve 10, the cylinder beingprovided with an upper open end and a closed lower end E8. The lower endI8 is formed with a vertical bore 8% forreception of the lower terminalof rod 38, the bore 80 having a counterbore 82, within which a lockingnut 84 is seated.

Laterally arranged ports 86 and- 8 8 are formedin the side wall of thecylinder, adjacent the end wall I8, and communicate the cylinderwith thecontainer, when the cylinder and sleeve are in their rested position, asseen in Figure 2. -It will be noted that the lower edge 90 of the sleeveis bevelled and constitutes a valve for closing the ports 86 and 88,upon upward movement of the cylinder 16, as will be .described. A spring.92 is housed within the sleeve.- 70, the spring :bearing at one end onthe lower edge of the tube 60 and engaging the inner surface of theendwall :18 of the cylinderto resist the movementof the cylinder upwardlyon the tube, :in cooperation withthe spring M.

. flexible spout 94 is mounted on the headill,

the spout being provided with ,;a connectingtube -95 having its threadedend Bathreadingly engaged in the outer threaded, end of ;a passageylfiil transversely; formed in the head and communicated with the passage32.. An annularstopllll is formed on the tube 96 to limit-theinsertionof .theanchoring threaded; end in therpassage. J

A' check valve assembly I02 is provided and is operatively interposedbetween, the tube 96 and .-.the;pass'age 32, the check valve assembly[82 including. a spring retainer l 04 transversely disposed in thepassage I86 and spaced inwardly of the outer threaded endof the passage.Aispring H26. ;is;seated in the retainer and supports a-ball lBS,normally seated in the valve-seat l lt formed at the inner, end of thepassage IDOL 4 check valve, the fluid passing through the tube 96 andthe flexible spout 94. Upon the exhaustion of the fluid, the check valvewill automatically reseat itself and, the springs 14 and 92 willautomatically effect a vacuum stroke of the cylinder. As thetelescopically arranged cylinder and sleeve return to their restedposition, after completion of the power stroke and automatic reseatingof the ball I08, vacuum will formdn the passage 32 in the tube, so thatas the cylinder moves down- I -wardly away from the sleeve, the sleevebeing held -by the'flange l2v bearing on the shoulder 66, -,the ports 85and'88 will again establish communication between the cylinder andcontainer and, due to the vacuum therein, the cylinder and tube willimmediately be filled with the fluid.

While the dispenser is particularly and especially designed fordispensing fluids having a high viscosity, obviously, any type of fluidsmay .Prior to the useof the-dispenser, thecylinder and vsleevewill bein.,their ;relative positions-,as :seen in Figure 2, the portspili; and88 of the cylinder: establishing communication between the .cylinder"tube and ,the container, so that a pre- -'determined-amount of fluid ishoused within the cylinder and-tube.
